AutoMeter WIRE HARNESS, TACHOMETER FOR MODEL 8199-05702 5258

Description:

Add this optional wiring harness to our ultra lightweight carbon fiber racing tach model 8199-05702 to enable the ability to interpret a digital RPM signal (which is common to most conventional performance ignition systems and ECU) instead of the NASCAR McLaren ECU CANbus which the tachometer is set up for by default.
